Query loop: Clarify the Max page to show setting

[afercia]

Description

Noticed while working on Discovered while working on #63020

In the Query loop block, the 'Items per page', 'Offset', and 'Max page to show' settings are grouped together.
Currently, they're in a popover that opens from the block toolbar. In #63020 they will be moved to the Inspector panel.

Regardlessof their overall placement, I'm not sure these settings should be grouped together.

• 'Items per page' and 'Offset' are more related to the Query properties.
• 'Max page to show' is more related to the Pagination links.

As a useer, the 'Max page to show' setting isn't immediately clear to me. I'd tend to think this setting should be better placed, probably in its own section as suggested also by @carolinan
Also, the descriptiokn:

Limit the pages you want to show, even if the query has more results. To show all pages use 0 (zero).

doesn't clearly explain this setting is about the pagination links. While 'pagination' may be a technical term to avoid, I'd think this setting should be better explained.

Nnte: in #63020 I'm fixing also a setting name typo where I guess 'page' should be plural 'pages' -> 'Max pages to show'.

Step-by-step reproduction instructions

• Add a Query loop block > Start blank > Title & date.
• Click 'Display settings' in the block toolbar.
• Note: after Make usage of the settings icon more consistent #63020 these settings will be placed in the Inspector panel.
• Observe the 'Max page to show' setting is grouped together with 'Items per page' and 'Offset'.
• Observe both the setting name and its description don't clarify very well this setting is related to the pagination links.
